On FC5, $HOSTNAME appears to be set in /etc/rc.d/rc.sysinit.
Of course, rc.d and rc.sysinit don't appear to exist on ubuntu.
I think you mean to reference /etc/hosts, not /etc/hostname

On FC5 (and RH derivatives) HOSTNAME is set in the /etc/sysconfig/network
file. I know that debian derivatives don't do it that way.

I can't find anywhere on ubuntu that HOSTNAME is set, except in
/etc/pcmcia/network and /etc/pcmcia/network.conf, which shouldn't come into
play (I wouldn't think) with a PCI NIC card.

I'll go now, seeing as I'm pretty much useless regarding this problem.
